I would think with eight bent pushrods there is a good chance of other damage. You could try backing off the rocker arms and doing a leakdown test to see if the valves are sealing properly. But to acurately check the guides and valves I would pull the heads. Is there a chance the timing chain is off?

did you bend 8 random pushrod ?? ,or all8 intake ,or all 8 exhaust ??..sounds to me like a cam mis-time problem ..there is a formula for setting valves cold ,with engine off .i have used it several times ,and it works great , no oil spray ,no oil stink on manifolds etc , if you have access to an older 80's/ 70's MOTORS manual ,it tells you how . if you can't find one locally ,i can research /recite the procedure ,but my book is at our car club shop ,but i'll have it in a few days ,if you' not in a hurry ..other advise is good ,back off the valves ,do a compression ,or leak down test ,if you have little ,or no ,or low compression ,i'm afraid you are in for a tear-down ..sorry for your luck ..jim p ..

Thanks to all whom replied. thats what I was afraid to hear. Im jumping in to the tear down tomorrow 3-27 Ive got a couple days weather permitting. By the way Ive bored this motor 30 over flat tops,480 lift,305 heads blended to match the 350 bore,matched intakes,port&polished them Its for 79 malibu curious to see the outcome. Not sure which push rods.done had them out before I realized it. PS.it stinks not having a garage thanks again

I've seen a lot of guys, including myself once or twice, put in distributors wrong on the first shot (usually 180 out) and have yet to see it wipe out a set of pushrods. There may be a first time for everything, but I haven't seen that one yet. Good luck with the tear-down.

Sorry for the misunderstanding reddwarf, I just didn't want him thinking his distributor being out caused the damage and maybe overlook something else. We try to write as clear as we can, but mistakes happen. I misinterpreted, sorry.
